On my nearly new Ridley CX bike, the front brake judders really badly when I apply any sort of power to the lever. Its scary!

I am running Avid Shorty 6 cantilevers with 2003 Ultegra levers/shifters. The rear brake is fine.

I have tried no toe in, front & back toe in but I still get the judder. The headset is tight and the forks are not light weight so shouldnt flex.

Pic of bike here.

Does anyone know how I can stop the judder please? Would a V Brake help? Would it work?

I'm not sure what I did but I used to have the same problem. I know one of the things I did was the toe-in and I think the other one was scrubbing down the brake surface on both the pads and the rim. Try to get all the gunk out of it.

I had the same problem on my old Redline. Tried everything mentioned above and it didn't solve the problem. After careful inspection, I discovered that the canti mount studs were not evenly tightened. Factory paint covered up the base and it wasn't noticeable until I measured them. One of the mounts was 2mm out from the other. I removed the stud, faced the mount area on the fork and re-torqued it until the 2 studs were even. Wala! no more brake studder. Also try steel wool on the brake surface of the rim to remove any (for lack of a better term) sticky spots were the pads grab more. Hope it helps.
Clean rims, make sure headset is tight andatpjunkie

toe the pads HUGE. also Avid has a new compound pad that works better. I had Avids as well with same problem. The number of posts has been amazing. Personally I don't think that much effort should be needed to get a top of the line brake to work. I switched to Spooky's and am quite happy. I haven't touched them or the rims (muddy rides excluded) since I set them up.
